generate your gitlab-ci from a template so each pipeline has its own job
dependency. The duplication won't hurt you if it's expanded through
templating and it gives you fine-grained running of the manual jobs.

We're using this in ci-templates/libevdev/libinput for the various
distributions and their versions so each distribution+version is effectively
its own pipeline. But we only need to maintain one job in the actual
template file.
